I won't say who wrote it, for obvious reasons, but part of the post mentioned one of the main differences between SF cons and furry cons: there's more art and creativity at the latter. SF cons mostly feature fanboying over TV shows and books, while at furry cons lots of people carry around sketchbooks and art supplies.
Not to say that furries don't have their share of fanboys or are better than SF fans, but yeah, I see the point. I've always thought furry fandom was something special. I guess misunderstandings over that idea is what lead to arguments that include comments along the lines of "Furries aren't the only subculture out there, ya know!" I know. But there's something special about us, so there! :}
